[QUOTE="BryanLitz, post: 355635, member: 7848"] The effects of altitude are captured in the Air Pressure input. If you hold the mouse pointer over the word 'Pressure' on the program, a table will pop-up that tabulates the air pressure at altitude. You can pick the pressure that corresponds with your altitude. This was done intentionally because altitude and pressure effects are commonly misunderstood and miss-applied in ballistics programs. This is the best way I could think of to handle it. The caliber, weight, and BC are all independent inputs. You have to input all three. The program shows you the form factor of the bullet which results from the above 3 properties. A G7 form factor less than .98 is pretty good (low drag profile), greater than 1.1 is pretty bad. Your questions about G7 BC are all answered in this article here on LRH: [url=http://www.longrangehunting.com/articles/berger-g7-ballistic-coefficient-1.php]Berger Bullets' Move To The G7 Standard BC[/url] You are correct in the assumption that the program has to be capable of using the G7 BC. Using a G7 BC in a program that's not set up for it will cause your computer to melt down:) -Bryan [/QUOTE]
